Eric, meanwhile, shared the same photo with a simple note. "Mother and Son," he wrote.

The pair have been vocal about their pursuit of a family and have been vocal about their infertility struggles, but couldn't contain their joy in York's birth announcement.

"As we thank the angel of a woman that carried our miracle baby boy for us, we pray for everyone who struggles to reach this joyous milestone," Tyra wrote when introducing her son. "York Banks Asla, welcome to the world."

Congratulations to the family!
